Helping prevent cryptogenic stroke reoccurrence through the detection of asymptomatic A-Fib

Cryptogenic strokes are types of strokes without any clear cause1. Multiple underlying factors can cause cryptogenic strokes, adding to the difficulty in performing an accurate diagnosis. A stroke occurs when the blood supply to the brain is interrupted, hence, heart rhythm and cardiac health are major risk factors. Vasculitis, endocarditis, or complications from asymptomatic atrial fibrillation (A-Fib)2 are implicated in some cryptogenic strokes.
  • Approximately 1 in 3 ischemic strokes are cryptogenic3.
  • 50% of strokes are embolic strokes of unknown source (ESUS)2.
  • More A-Fib cases are caught the longer the patients are monitored4,5.

Administering anticoagulation medication is effective at preventing recurring strokes when A-Fib is connected3. This means that catching A-Fib is crucial to knowing which treatment intervention is best at preventing stroke reoccurrence.

The CardiacSense watch is a certified medical device for continuous (24/7), non-invasive, real-time monitoring and detection of patients with A-Fib, with a sensitivity and specificity rate of above 95%6. The device contains a photoplethysmograph (PPG) and a one-lead electrocardiogram (ECG), giving it the ability to measure heart rate and heart rate variability constantly and accurately. In a comparison study, all A-Fib events detected by physicians based on Holter ECG were also detected by the CardiacSense watch5.

The CardiacSense watch provides accurate data for healthcare providers through the easy-to-access Physician portal, facilitating their diagnoses and treatment decisions.

Wearing the CardiacSense watch can help healthcare practitioners make the right decisions to prevent reoccurrence of strokes linked to asymptomatic A-fib.
